To all whom-it may concern:

Be it known that we, HARTWELL W. WEBB, a citizen of the lUnited States of America, arid a resident of Cresskill, county of Bergen,

and State -bf New Jersey, and EDWARD lH.,

'STIC-nuns, a, citizen 'of the United States of America', and a resident of Edgewater, county of Hudson, and State of New Jersey, have` invented certain new and useful Improve,

ments in Mixers' for Gaseous Fluids, of which the following isa specication, reference being had to the accompanying `drawings, forming a partthereof..

Our invention relates to mixers for gaseous fluids and. particularly to mixing devices. adapted to-be employed in conjunction witha carbureter fory reparinga gaseous charge forfuel, motive uid,l and similar purposes.

Our invention consists in certain novel features of construction and arrangement of parts, as will presently be explained and particularly .in a novel form and construction of the rotary `paddle or fan wheel employed.

In order that our invention may be thoroughly understood, we will now-proceed to describe an embodiment thereof, having ref.- erence tothe accompanying drawings illustrating the same, and will then pointent thanovel features in claims.

lin' the drawings: Fi re lis a view in central vertical longitu inal section through agas mixer constructed in accordance withl `our invention, showing the same as supported between the flanged connections of pipes.` Fig'. 2 is an end View thereof. Fig. 3 is 'a transverse sectional view of the gas mixer. upon the plane of the line 3-3 in Fig. l. Fig. 4, is an edge lview of the paddle or fan wheel. Fig. 5 is a face vi'ew of a slightly modified form ofl paddle or fan wheel employed. Fig. 6 is a similar view .of a further modification. Fig. 7 is a detail view in side elevation of'a single addle or fan wheel blade of further modi ed form..

Fig. 8 is a detail view showing the laminated The gas mixer as a whole comprises gen; erally two elementsflj-e statiiaiy support' and a rotatableelement including fan 'or paddle blades. The stationary,v element in :currents which iow in the paddle or fan wheell of the spider arms are-connected. The hub 10, spider arms 11, and ring 12 are conveniently formed from aA flat sheet, constituting an-ord1nary flat metal stamping, as will be,read1ly understood by referencefto the .drawingsv Secured to the hub 10 by means of a central bolt or stud 13 is a bearing element 14.. As a matter of construction' the threaded portion of the stud 13 is preferably' tapped into the hub 10 of the support,

' and a lock nut 15 is employedto lock the parts in their assembled position.

The rotating element comprises a paddle orfan wheel 16 and a hub 17 secured thereto and constituting a bearing element complef` mentary to the bearing element 14. The hub 17 is cup-shaped, being formed with a base 18 or shouldered portionwhich bears against the rear face 'of the fan blade, and lwith a within a central opening in the paddle or fair wheel. .After the parts have been so assembled the extremity' of this reduced neck portion is turned over as appears at 20 in the drawings, the hub and paddle wheel being -therebysecurely fastened together.

. reduced neck 19 arranged tov be received' Before the hub is mounted in position.

upo the bearing Aelement 14 two sets of balls 21e-22 are mounted inposition2 the A,beariifig surfaces ofthe element 14 constltuting cones for the said balls, and the interior face of the hub 17 'constituting whereby an .efficient bal bearing is provided about which the fan or paddle wheel may rotate.l

A flange er washer 23 is disposed between the head ofthe stud or bolt 13 and the ro tating element, whereby the same may be cd'nned in lits position after the parts Ahave e54 raceways therefor,

been properly assembled. This washer has i v-a further function as willpresntly appeaic'l, irt eng carrie viz., to revent dust and into the ll bearing by and with the gaseous direction of the arrow`24= in Fig. 1.' N,

The blades lof the paddle orfan wheel are arranged oblique with respect to the plane of rotatien'of the wheel, but preferably the obliquitI of the several blades is not alike. Convemently the blades may comprise two sets, the blades of which 'alternate .with each ther, all of the blades of each-set beingV similarbut arranged at a different angle to'thef blades ofthe other set, for instance, in an los "y as' oveii'ungsY te f yleonsiderable extent :the

tint fofmuaawau and the rearwardex esionof thfgbearing element 14; A guard oftx's chaactgrl" s 'i 5 been fund to be very esse tial` as otherwise the' ball bearings cut out in a`very short What we claim is:' i 1. In a mixer-for 'gaseous fluids, the combination lwith a supportingelement, of'a fan or addle wheel mountedl to'rotate freely wit respect thereto, the said fan" or paddle l Wheel having a.;plurality of- "obliq'u'ely dise posed blades havlng different pitches'. f 2. In a rnixer forgasepusiiuds, the com bination with a' supporting element, v'of a fan or addle wheel mounted to rotate freely Wit respect thereto, thel said fan or paddle wheelhavingtwo sets of obliquely disposed zolblades'arranged Ialternately with respect to each other, the blaldes of one set having dif ferent pitches to, theblades of the otherset.

4.' In a mixer for lgaseous fluids,the combination with a supporting element, of a fan i or paddle wheel mounted to rotate freely,

with respect thereto, the said-fan or "addle wheel having a plurality of oblique yfdis-r posed, blades Jhaving different pitches, the" edges of the said blades being serrated p 5. In a mixer for gaseous fluids, the pombination with a supportin element, of a fan *on/paddle wheel mounte to rotate freely;` `with respect thereto, the said fan or paddle` 40 wheel having obliquely. disposed blades'the,

side edges of which -a re.-notched to'jform l teeth between them, the teeth 'upon opposite` sides of 'the said blades being 1n staggered-v relation with each other.
